WHEEL-TIRE.

Application filed June 22, 1915. Serial No. 85,604.

To all whom it may concern:

' Be it known that I, PAUL S. HALL, a citizen of the United States, residing at Austin, in the county of Mower and State .of Minnesota, have invented new and useful Improvements in lVheel-Tires, of which the following is a specification.

The invention relates to an improvement in tires, particularly to a resilient tire involving the use of spring elements for the supporting means.

The improved tire embodies a construction involving essentially a means for securing to the felly of the wheel a holding member of particular formation for removably supporting a series of spring forming elements and also for holding in place the fabric casing; the spring'forming elements being constructed to provide a reinforce of the casing at the wear point.

The invention in the preferred form of details will be described in the following specification, reference being had particularly to the accompanying drawings, in which r Figure 1 is a longitudinal sectional view through a portion of the improved tire; Fig. 2 is a transverse view through :the same; Fig. 3 is a perspective view of one section of the clamping member; Fig. 4 is a perspective view of one of the spring elements; Fig. 5 is a perspective view of one of the stop abutments; Fig. 6 is a broken perspective view showing the connection' of the clamp member to the felly and'thc connection of the springs to the clamp member. Fig. 7 is a view in elevation of the completed wheel.

In carrying out the invention I provide what is termed the .clamp member comprising double sections of annular formation adapted to fit more or less closely to the felly 1 of the wheel. The sections 2 forming the clamp member each include a flat plate like portion 3 approximating in width half the width of the felly, which plate member is'at' its inner edge formed in a. return bend upon itself to form a clamping lip 4. The outer edge of the section is outturned to provide a flange 5. Securing plates 7 are riveted to the clamp member, being secured to both sections and having an extension 8 adapted to be turned in against the felly and to besecured thereto by a bolt ,9. One of the'secur ng plates Specification of Letters Patent.

may, if desired, bevof materially greater width circumferentially of the felly e than the others and the overlying or meeting ends of the 'clampsections secured thereto, 1

ltis of course to be understood that any desirable number of securing plates are used and that preferably the felly is recessed to receive them as shown at 10.

Carried by the clamping member are spring forming elements including spring sections 11 bent into form approximating that of the completed tire with their free ends at the inner portion. Diametrically opposite the free ends the spring section is formed to provide an inwardly offset portion 12 to which there is removably secured a stop abutment. The latter comprises a 'metallic strip bent to form a loop end 13 to snugly embrace the portion 12 of the spring element, the stop abutment has a pro ection 14 which extends within the spring section and terminates at its inner, end some distance outwardly beyond the free edges'of the spring section, the J function'of this stop being to prevent, through load strain, excessive spreading of the" spring element, as will be obvious.

After the clamping member is secured in place as'described the spring elements are applied by inserting the free ends of each of said elements beneath the lips 4: of the clamping member sections, this operation holding the spring elements in place, there is provlded a suflicient number of such elements to encircle the wheel and form in effect a tire-like structure. A casing 15 of suitable fabric is arranged to envelop the spring-elements, the offset portions 12 forum ing a channel circumferentially of the wheel to receive a thickened portion 16 interiorly of the casing which provides additional material at the wear points, and at the same time serves to center the spring'elements andhold them in alinement. The edges of the casing 15are provided with loop terminals 17 which are transversely cut to pro-V vide what may be termed a series of independent loops. A wire 18 is passed through the loops of each side of the casing and eX- tends around the clamp member immediately adjacent the flange 5, the ends of the wire being connected by a turn-buckle 19 for tightening, the flange 5 being interrupted to permit the position of the turn-buckle as as described'the application and removal of the casing is facilitated. V

In; the improved. tire itiwill be obvious that the load strain is resisted by the spring size to accommodate the increased dimensions of the spring elements.

, WVhat-isclaimed' is:

1. A Wheel tire including aclamping member made up of separable sections adapted tobe disposed circumferentially of the-Wheel, the inner edge'of each section being'return'ed upon-itself to'form a clamping lip,-the outer edge of each sectionbeing outt irned to form aflange, a series of independentspringqelements having their ends engaged beneath the lips of both sections, and a casing encircling the spring elements, and held ithin the outer flanges.
